Reborn in the end of the world, I scavenged in the empty city and bought for free

In fact, Gu Tongwan had previously considered whether the base’s inability to grow tasty crops was related to the soil corroded by acid rain. After all, highly corroded soil cannot be used for planting immediately under normal circumstances. However, the base seems to have developed some special fertilizers that can promote the growth of crops.

However, this type of fertilizer also has a disadvantage. Although it neutralizes the corroded highly acidic soil, it also destroys the original soil structure to a certain extent. Therefore, the crops grown are not only of varying quality, but it even changes the shape and taste of the crops themselves.

In recent years, the base has been trying to find suitable soil for growing crops in the big forest in the north, but unfortunately, in order to obtain fertile soil, it is necessary to go deep into the danger zone or even the restricted area, and it is difficult to collect a large amount of soil at one time. Originally, the base had sent a professional team, at least dozens of Dongfeng pickup trucks into the forest to collect this kind of soil, but unfortunately, the risk of entering the forest is too high. As soon as they entered the danger zone, they were attacked by mutant animals. Even after entering the "Valley of Death" between the danger zone and the red zone, the entire team lost at least half of its combat power. Therefore, the base’s top management had to temporarily abandon the plan to obtain soil from the danger zone.

Of course, they have also tried to start with the soil in the safe area. After all, although the vegetation in the entire safe area is not as strange as that in the danger zone, its vegetation is also extremely lush and can still appear lush and green under the corrosion of acid rain. Obviously, the soil structure here is not normal.

Unfortunately, after research, it was found that the soil in the safe zone is not suitable for growing crops, because the lower layer of the soil here is a hard rock layer. If you want to dig deep, you will need a large excavator, and this will also affect the mutant beasts deep in the forest. If not handled properly, it will cause a large-scale beast tide.

Faced with the possibility of an attack and only a small amount of topsoil available, the base eventually abandoned the plan.

However, some people tried to bring some soil from the safe zone back for planting. Unfortunately, no matter what plants were planted in this soil, they did not grow as wildly as in the forest. So some people speculated that the mutated plants in the big forest in the north were a kind of post-apocalyptic animal and plant mutation, which was not only related to the soil, but also had a direct connection with the climate and environment there and some kind of energy source.

Yan Fan also mentioned this on the way. He actually couldn't understand why Gu Tongwan would take the risk and drive to dig up this useless soil.

"The soil in the safe zone is really not very useful, so I want soil from the danger zone, or even the Death Valley."

She said this calmly in the car, without even much emotion on her face, as if this matter was as simple as eating.

In fact, Yan Fan was not quite sure. The blood vine in her body was the same plant as the "giant blood vine", the most mysterious plant that had been entrenched in the Death Valley for a long time. The blood vine seeds obtained from the system might be a more advanced mutant plant than the blood vine in the Death Valley. If the blood vine in her body could successfully suppress the blood vine in the Death Valley this time, perhaps she would be able to get more soil there or discover something unknown.

This was what she discovered during her last hunting activity. The closer she got to the Death Valley, the more active and eager the blood vines in her body became than ever before.

In addition, she had seen similar blood vines in Haicheng before, and the blood vines in her body that time were just as restless, as if they were eager to devour the other party.

Of course, all of this needs to be kept secret from Yan Fan. She didn't think that she could enter the Valley of Death today, but she did need to collect some soil from the danger zone. She wanted to try to combine the soil from the danger zone with the soil in the space, and then plant the seeds given by the space system. She didn't know if she could grow normal crops in a non-space environment.

Gu Tongwan pinched some soil in his hand, then brought it to his nose and smelled it. He found that the soil here not only had the earthy smell itself, but also a faint fragrance, but this fragrance was not the scent of flowers, but more like the smell of refined oil.

Although it is still unclear what the structure of this soil is and whether it is suitable for successful planting, we cannot return empty-handed since we have already made this trip.

He took out a dozen snakeskin bags he had prepared from his backpack, at least fifty or sixty bags. He glanced at the time and saw that it was seven-thirty in the morning. The sun had risen completely, but because of the huge vegetation of the big forest in the north standing on both sides, everything in the forest looked gloomy.

Gu Tongwan took off the folding engineer shovel from his waist, stretched his limbs slightly and did some muscle stretching exercises, then began digging in the soil layer that was determined to be suitable for digging.

There are many advanced mutant animals in the danger zone, but she still has Tutu by her side. She then released a dozen blood vines in her body in advance, so her safety can be guaranteed temporarily. After all, the blood vines and Tutu have strong perception, and they can remind themselves in time once an advanced mutant animal appears. However, if it is a mutant animal of a lower level than them, they will not dare to approach easily because of the strong aura of supernatural powers here.

But I have to say that this digging work is really tiring, it is completely a physical job. Fortunately, the soil here is relatively thick and soft, so it is not too difficult for the engineers to shovel. But even so, they are still exhausted after shoveling three bags.

It would be nice if there was some handy or convenient cheating tool...

This thought only flashed through her mind, but she immediately flashed into the space.

It has been a long time since she last checked the system mall in the space, because she had always disliked the things here as being expensive and impractical. In addition, there were not many points left after the last upgrade of the space. Currently, she only has 2089 points left. At this stage, she has to find a way to increase her points as soon as possible.

But if you want to gain points, you must get the crystal core. Although you can take Tutu to hunt some mutant beasts similar to B and C levels, the most important thing at the moment is to run your own shop well. At least wait until the profit of the shop gradually stabilizes before considering upgrading the space.

Currently, there are eighty or ninety kinds of goods on the shelves of the space system, but each one is expensive, and most of them are disposable goods. Permanent goods are not only scarce but also expensive.

[Chewing Gum] The price is three hundred space points and it is a one-time item.

Spitting out the food after chewing it can slow down the movements of people within a 30-meter radius, and the effect lasts for one minute.

This seems to be quite useful for escaping, especially when encountering high-level psychics or mutant beasts, it can indeed be used as a secret weapon.

[Folding Bed] The price is 2,800 points and it is a permanent product.

After lying down, you can fall asleep within one minute without being disturbed by nightmares, which can ensure the quality of sleep. It can be used ten days a month, each time for eight hours.

If those who suffer from insomnia knew about this thing, wouldn't they treasure it? But for someone like her who could fall asleep almost as long as she touched the pillow, it seemed to be of little use, and the price was too outrageous.

[Embroidery needle] The price is 1,500 yuan and it is a disposable item.

It can mend all hard objects, including living things, and is a special product.

[Violent Hammer] Price: 400, one-time item

It has powerful destructive power and can easily destroy a pickup truck weighing dozens of tons.

[Fragrance Enhancer] Price: 500, one-time item.

It can remove all special odors within a range of one hundred meters.

【Flash bomb】Price: 600, one-time item.

It can make the area within a radius of thirty meters as bright as day, and the light lasts for two minutes.

If the above products are considered normal, then some of the following products have already exceeded Gu Tongwan's cognition.

【Twisting Candy】Price: 500, one-time item.

The object consumed can be made to twist continuously for five minutes, and remain in a highly excited state.

[Stinkbug] Price: 900, disposable item.

It flies slowly, but can produce a smelly gas that can make people faint. The concentration of the odor is ten times that of a weasel and can last for thirty seconds. Users must be careful not to get themselves fumed.

Gu Tongwan's expression changed from calm to frowning and then to speechless, and his fingers quickly swiped across the product pages of the mall.

At this moment, her brows relaxed and a hint of joy flashed in her eyes.

Finally found what I needed.

Surprises in life often come so suddenly. Just when you think the mall is full of things you can’t use, an unexpected surprise appears.

[Mini Excavator] The price is 1,200 points and it is a one-time item.

The volume is one-fifth of that of an ordinary excavator, and it can simulate the functions of an excavator to dig soil, dig wells, or even dig anything you want to dig. But remember, materials with a hardness higher than diamond cannot be dug. The maximum digging depth is three meters. It can carry 30KG each time and can operate continuously for eight hours. After eight hours, the digging effect will be lost and the function will become invalid after the continuous operation time expires.

Gu Tongwan began to think in his mind that although this thing looked expensive, the eight hours of working time could actually be disassembled and used separately. This way, he would not have to concentrate on continuous work in one day, and it would be more convenient for him to use.

Clicking on the detailed picture for a closer look, I found that the entire excavator is about 30 meters high and meters wide. Although it can only carry kg at a time, the excavation speed is so fast that each excavation only takes less than a minute. So if it is used for an hour, at least one ton of soil can be obtained.

Although she had not calculated specifically how much soil was needed to cover the entire backyard vegetable garden, her initial plan was to fill up the entire pickup truck. Each snakeskin bag weighs 50 kg, and at least 50 bags of cement can be transported in one trip. However, she was not worried that the pickup truck would be overloaded, after all, she still had the cheating tool of portable space.

I tapped the product page with my fingertips, and instantly saw that my balance was immediately consumed by 1,200 points. However, an excavator icon appeared in the lower right corner of my warehouse page.

It would be better not to let Yan Fan know about the mini excavator for the time being. Gu Tongwan released two blood vine branches to observe the situation nearby. Yan Fan and Aoao would be out for at least an hour before coming back, so she wanted to take this opportunity to try out how much mud this excavator could dig out.

After the excavator icon passed through his mind, a real mini excavator immediately appeared half a meter away. The manual said that he needed to press the red button on the side to make the excavator work normally. There was another simpler operation. The excavator was also equipped with a remote control with two red and green buttons on it. The red button was for start and the green button was for pause. After pushing the mini excavator to the appropriate position, Gu Tongwan pressed the red button on the remote control in his hand, and then he did not forget to put the [silencer] he bought before on the excavator, so that the excavator could be silent during operation.

The excavator was very efficient. In just five minutes, a lot of soil was pushed in front of Gu Tongwan.

She was not idle either. She started shoveling the soil into the snakeskin bag. After about half an hour, the excavator had dug a deep pit with a diameter of two meters and a depth of about one meter.

At this rate, we will probably finish today's task in another half an hour. After all, digging is not difficult with an excavator. The more troublesome part is shoveling the soil. It takes a lot of effort to fill the sack.

Yan Fan's training time was extended this time, mainly because he and Aoao encountered an extremely rare B-level mutant frost rabbit near the danger zone. Although the frost rabbit is only a B-level mutant beast, its living environment is very harsh and remote, so its number is extremely rare. In addition, the crystal core in its body is a rare source of energy for those who use ice or frost-type abilities. Therefore, the frost rabbit can be sold at a high price even in the black market.

Although the Frost Rabbit is an ice-type mutant, it actually looks very similar to a normal white rabbit, except that it has some light blue fur on its tail and back, and its eyes are beautiful light blue like glass. The reason why this mutant rabbit is given the name "Frost Rabbit" is because it can use ice-type abilities and can create a frost field in a small area.

But the most amazing thing is that the fur of this rabbit looks fluffy and soft. It is said that the fur of the frost rabbit can be made into gloves or scarves that can keep warm in frost lands. It seems that for this reason, the frost rabbit can still survive even in the north where the temperature is dozens of degrees below zero.

The Frost Rabbit is agile and can use ice powers appropriately, which is indeed a big challenge for Yan Fan, who is only at C-level. Although Aoao can easily catch B-level Frost Rabbit, this time Yan Fan did not let Aoao help him. Instead, he tried to catch it by himself relying on his own powers.

Fortunately, the frost rabbit was an underage rabbit and could not use its supernatural powers very skillfully. After some effort, Yan Fan finally captured it.

When Yan Fan and Ao Ao turned back, they saw the big pit in front of Gu Tongwan from afar.
